User event task Issue

How Can i Configure User Event Task in PLC Next Engineering?

I want to Call Some of My POU on Bit which is available in my PLC Logic or Digital Input Can i Use this Feature?

There was a discussion about this feature back in 2019, here:

[url="https://www.plcnext-community.net/forum/#/discussion/497/user-event-task"]https://www.plcnext-community.net/forum/#/discussion/497/user-event-task[/url]
Unfortunately it seems that the EVENT_TASK function block mentioned in the help system has still not made it into PLCnext Engineer. In the mean time, it is possible to trigger user event tasks from C++ code, as described in the other thread.

I Read this Thing But i dont know where i can write C++ Code.

Can you Please help me in that.

Where i can Write 

#include "Arp/Plc/Commons/Esm/RtEventManagerProxy.hpp"

Arp::String eventName = "EventName";
Arp::Plc::Commons::Esm::RtEventManagerProxy& rtEventManagerProxy = Arp::Plc::Commons::Esm::RtEventManagerProxy::GetInstance();
this->rtEventPtr = rtEventManagerProxy.GetEvent(eventName);

if (this->rtEventPtr != nullptr)
{
    this->rtEventPtr->Set();
}

this stuff?
